Why are there seven days in a week, 30 days in a month and 365 days in a year?

The origin of the seven-day week system

When Hammurabi was in power, leap was stipulated by decree, and then gradually had a fixed cycle. They have been able to distinguish the five planets from the stars, and they have observed the orbits of the five planets quite accurately. They associate the star with God, and the star is God, so they use the symbol of the star to represent the concept of God. There is a star god on duty every day, and there is a seven-day cycle, so seven days are regarded as a week, named after the seven planets: sun, moon, fire, water, wood, gold and earth. The so-called "week" is the date of the stars. Later, with the progress of science, the superstitious color added to the week was removed. The weekly system has been used to this day, which is the origin of the current seven-day weekly system. A month is 30 days, because the moon goes around the earth and the full moon is 30 days. There are 365 days in a year because the earth revolves around the sun, and the rotation of the four seasons is 365 days.
